It is a world where animal hybrids coexist with humans. Animal hybrids look similar to human but have base animal's characteristics like ears, tails, appetite and abilities. Herbivore hybrids have big appetite, and are very gassy due to their fermentative digestive system. The bigger the base animal, the gassier they are. Their farts are also visible due to how thick the gas is, varying from yellow to brown. Female hybrids are way gassier than males.
